MacFUSE + sshfs :: Really Great
Now I can just mount the company server via SSH, I can double-click on any of the files and edit them locally and save them back over the network as securely as possible (for me). It works well enough for most operations, although for whatever reason, I couldn't install fonts from the mounted volume.
Another stumbling block is, that for each new host you need to manually connect with ssh the Terminal.app first, because ssh will prompt you like this:
The authenticity of host 'oswald.mulle-kybernetik.com (212.202.151.202)' can't be established. RSA key fingerprint is 45:70:a5:f7:b4:84:f7:a1:18:b8:a4:64:bc:68:c0:24. Are you sure you want to continue connecting (yes/no)?and is not clever enough to figure it out. After you connected once successfully, it's no problem after that.
